Mechabellum [Test Server] Update 1.11x1 Patch Notes (27th May 2026)

Mechabellum's latest test server patch reins in Hacker control efficiency and cuts Battlefield Power durations in half.

Hacker mains are going to feel this one. Test Server Update 1.11x1 is now live on Mechabellum's public test branch, and the headlining change is a 0.9-second preparation delay before Hackers can seize control of a new target. Per the developer's note, that window hits light units hardest while leaving control efficiency over medium and heavy units mostly intact, so the unit isn't gutted, just less of a menace against fast, cheap swarms.

Vortex is also getting trimmed. The Grid Integration ATK modifier cap drops from 135% to 105%, and both Emergency Armor and Field Maintenance cost 50 more each. On the flip side, Scorpion's Convergent Fire upgrade gets a meaningful buff: attack interval drops by a full second and the cost falls from 200 to 150, which should make it a more viable pick. Battlefield Powers take a significant hit too, Smoke Bomb and Acid Blast both drop from two-round to one-round durations, with Acid Blast also halving in cost to 100.

This is a test server patch, so nothing here is final, but the Hacker change in particular looks like it could reshape how early aggression plays out once it hits live. Here's everything that changed.
